The change in the taste of miso (soybean paste) in the course of the fermentation process has been studied using a multichannel taste sensor, which utilizes lipid membranes as a transducer of taste substances. It is found that the response potentials of membranes made of dioctyl phosphate and oleyl amine increase linearly with the number of days of fermentation of miso, while they show only a slight increase for ripe miso products. The amino-acid contents and titratable acidity also increase with length of fermentation; high correlations between the sensor output and these quantities are pointed out. Therefore, the fermentation of miso can be easily monitored using the taste sensor.
